"The atoll is comprised of four large coral islands which enclose a
shallow lagoon; the group of islands is itself surrounded by a coral
reef. Due to difficulties of access and the atoll's isolation, Aldabra
has been protected from human influence and thus retains some 152,000
giant tortoises, the world's largest population of this reptile." — UNESCO
